To all whom it may concern:

Be it known that we, FRANK ASHWORTH How, a subject of the King of theUnited 4 Kingdom of Great Britain and Ireland, and

resident of Noon Sun House, Whitworth Road, Rochdale, in the county ofLancaster,

England, and GRINDROD KERSHAW, a subject of the King of the UnitedKingdom of GreatBritain and Ireland, and resident of 62 Market street,VVhitworth, in the county of Lancaster, Englandgihave invented new anduseful Improvements in Winding-Machines, of which the followingis aspecification.

This invention relates to winding machines and particularly to windingmachines of the kind in which a roll kept revolving is employed torevolve a windingholder by friction against such holder or a spoolplaced upon it or yarn-or thread or twine or the like wound thereon.

The object of this invention is to insure that in machines of the saidkind yarn or thread or twineor the-like shall be wound into packagestruly of the form intended and to obviate the tendency hitherto experienced of packages of yarn or thread or twine or the like especially ofsoft yarn and of open wind to be wound or built of diameter larger thanthe intended diameter corresponding to the number of layers or coilswound at the-ends of the packages and especially at the smaller ends ofconical packages and at the ends of cylindrical packages.

This invention essentially consists in devices by which packages of yarnor thread or twine or the like being wound in contact with driving rollsare subjected to more intense pressure and wound more tightly thanelsewhere at the parts which tend to be wound or built of larger thanthe intended diameter corresponding to the number of coils 01 layerswound and by being subjected to more intense pressure and wound moretightly at those parts are prevented from there increasing in diametermore quickly than they ought.

This invention also comprises driving rolls of simple and advantageousformation for enabling winding to be effected under more intensepressure and more tightly at the parts of yarn packages which tend asUNITED STATES PATENT OFFICE.

aforesaid to be wound or built of larger than the intended diametercorresponding to the number of coils or layers wound.

Other features of this invention are hereinafter pointed out. I

In the description and claims following the word yarn is used to meanyarn or thread or twine or the like.

According to this invention opposite the end or each of the ends andadjacent parts at which it is'desired to check the tendency of a' yarnpackage being wound against a driving roll to be wound or built ofdiameter larger than the intended diameter corresponding to the numberof coils or layers of vided witha taper piece increasing in diameter inthe direction away from the adjacent part of the roll and in the windinof ajyarn package against the driving ro l first the yarn carrier andthenpart of the yarn pack:

age in process of formation is made to bear against the taper piecewhilebeing revolved and'the bearing and rolling of the yarn towardthelarger end of the taper piece" 85 and. cause the parts wound againstthe taper piece to be Wound under condltlons lnsuring .yarn wound uponit, the driving roll is pro- 1 that the length and tension of the yarnwound into such parts shall be such as to v insure that those partsshall not be of a diameter larger. than that properly corresponding tothe number of layers or coils of yarn wound into them. The tendency ofthe package to build or be wound unduly large toward and at the end isthus coun- 3' teracted by a resistance increasing in a correspondingmanner;

In the accompanying drawings which show illustrative embodiments of thisinvention, Figure 1 is a slde elevation of.a driving roll with a taperpiece at one end loose from the driving roll and increasing in diametera conical package of yarn bearing thereon. Fig. 3 is a side elevation ofa driving roll with taper pieces fast upon each end increasing indiameter outward toward the ends and a cylindrical package of yarnbearing thereon. Fig. at is a side elevation of a driving roll withtaper pieces increasing in diameter outward toward theends one of whichtaper pieces is loose from the driving roll and a cylindrical package ofyarn bearing thereon.

Fig. 5 is a side elevation of a driving roll with taper piecesincreasing in diameter toward the ends both of which taper pieces areloose from the driving roll with a cylindrical package of yarn bearingthereon.

The same letters of reference are employed to indicate correspondingparts in all the figures.

In the drawings. in each figure a is a shaft supported in any suitableway and revolved by any suitable means and b is a driving roll securedupon it. In each case represented, the driving roll 6 is formedcylindrical in part and of a tube 0 furnished with and secured by anysuitable means upon an internal boss (5 provided with a screw threadedhole receiving a screw 6 by which the boss d and the driving roll 6 aresecured in position upon the shaft a. f is a carrier for yarn or threadon which yarn is to be wound by the carrier 7* or yarn wound upon itbeing made to bear on the driving roll so as to be revolved by frictionagainst it.

The carrier 7' may be mounted in any suitable manner in the machine inwhich it is to be used. For simplicity and convenience of illustrationeach oi? the carriers f represented in the accompanying drawings isshown as mounted to be revolved about an axle 9 carried by a movablesupport is mounted in any suitable way in the winding machine.

in Fig. 1 there is provided at the end of the driving roll 5 which inuse is nearer the smaller end of the conical yarn package 2' in processof formation I a taper piece 9', which at its smaller end is shoulderedor reduced in diameter to enter the adjacent partcf the roll F) and isof increasing diameter in the direction away from the adjacent part ofthe roll I). k is a collar with a screw threaded hole receiving a screwZ by means of which the collar 1 0 is fixed in position upon the shaft ato hold the taper piece y' to the driving roll Z) while permitting it tobe turned upon the shaft a relatively to the roll I). The taperpiece 3'may be of any suitable material for example advantageously of vulcanizedfiber or of metal. The yarn to be wound may be single yarn or two ormore threads brought to the carrier 7 side by side and is preferablymade to reach first the carrier f and later the yarn package 2' woundthereon as closely as practicable arness being made to bear upon thetaper piece is driven thereby until the winding of yarn I has proceededso far that the layers or coils of yarn wound on the parts opposite tothe cylindrical part of the driving roll 6 are suiiicient for contactbetween the yarn package i being formed and the cylindrical part todrive the yarn package 2' and thereafter the surface speed of the yarnpackage .5 deterniines the speed of the taper piece j so that rubbing ofthe yarn against the taper iece j will be obviated so nearly that inuryto the yarn will be obviated. Until the winding of yarn on the carrier 7causes the package 2' in process 'of formation to bear on thecylindrical part the pressure of the package 2' i against the taperpiece j and is more intense in the parts against larger parts of thetaper piece and after the partly formed package 2' bears on thecylindrical part of the driving roll the yarn package bears and rollsagainst the taper piece throughout the winding of a yarn package 2' witha pressure more intense than the pressure with which the yarn packagebears and rolls against the cylindrical part of the driving roll 5 andmore and more intense toward the narrower end of the package a and theparts of the yarn package bearing and rolling against the taper piece jby rolling against it are subjected to other influences which are moreintense than those affecting the part presented to the cylindrical partof the driving roll and increase in intensity toward the larger end. ofthe taper piece.

Through the pressure and other influences which aifect the part of theyarn package bearing and rolling against the taper piece 7' increasingin intensity toward the larger and of such taper piece j and being moreintense against the taper piece j than against the cylindrical part ofthe driving roll Z) the yarn wound into the parts of the yarn packagebearing and rolling against the taper piece will be of such length andunder such tension as to insure that. such parts of the yarn packageshall not be of a diameter larger than that properly corresponding tothe number of layers or coils of yarn wound into them.

The parts of the yarn package wound against the taper piece will thus bewound. so tightly tn be prevented from becoming iarger than they shouldbe for the number of layers or coils of yarn wound.

For the winding of fine or soft yarns it is very desirable alrnostnecessary or the finest and s "test yarns quite necessary that taperpiece shall. be able to turned lit? relatively to the driving roll I)when the yarn package 11 is driven by contact with the cylindrical partof the driving roll I) in order that the difference between the surfacespeed of the driving roll I) and the smaller end of the yarn ackage z'may not cause the yarn to be rubbed or polished at the smaller end, ofthe yarn package. In

any case however in Whichrub'bing of yarn at the smaller ends of conicalyarn packages is of little or no importance the-taper piece and causesthe yarn package to be driven 7 provided at the end of the cylindricaldriving roll '6 may be made always to revolve turn for turn with it.

Fig. 2. shows a driving roll with a taper piece j in one with thecylindrical part of the driving roll .5. The taper piece j in this casemay very advantageously be formed by partly by the cylindrical part band partly by the taper piece 9' and the difierences of surface'speed ofthe parts of the driving roll I) and the parts of theyarn package incontact being greater causes more rubbing of yarn than in thecaserepresented in Fig. 1, but in other respects the action of the drivingroll I) and taper piece y' shown in Fig. 2

-is similar to that of those shown in Fig. 1.

' 'In Fig. 3 the driving roll I) is provided at I each end of thecylindrical part with a taper piece 7' in one with the cylindricalpartand v increasing in diameter in the direction away from the adjacentpart of the roll 6. Very advantageously the driving roll I) may beformed as a cylindrical tube and .be expanded in order that the taperpieces 3' may be formed.

The driving roll I) being made to revolve and the carrier 7 with yarnttached to it being made to bear upon the taper pieces is driven therebyuntil the winding of yarn has proceeded sofar that the coils of yarnwound onthe part opposite to the cylindrical part of the driving roll 55are suiiicient for the contact between theyarn package 41 and thecylindrical part to drive the yarn package 2' and thereafter the drivingof the yarn package i is eflected partly by the contact of the package2' and the cylindrical part b and partly by the contact of the package2' with the taper pieces. Until the winding of yarn on the carrier fcauses the packagei in process of formation to bear and roll on thecylindrical part of the driving roll Z);

the pressure of the package 2' bears and rolls against the taper piecesj only and with a pressure more intense in the parts pressed against thelarger parts of the taper pieces j and after the partly formed package71 bears and rolls on the cylindrical part of the driving roll I), thepressure of the yarn wound upon the carrier f against the taper pieces jwill be more intense than the pressure against the cylindrical part ofthe driving roll I) and will be more-and more intense toward the ends ofthe package 2' and the parts of the yarn package bearing and rollingagainst the taper pieces j by rolling against themare subjected to otherinfluences which are more intense than those affecting the partspresented to the cylindrical part of the driving roll and increase inintensity to:-

ward the=larger ends of the taper pieces 9;

Through the pressure and other influences which affect the parts of theyarn package bearing and rolling against the taper pieces j increasingin intensity toward the larger ends of such pieces j'and being moreintense against the taper pieces 7' than against the cylindrical part ofthe driving roll 6, the

yarn wound into the parts of the yarn package z' bearing and rollingagainst the taper pieces Will be of such length and under such tensionas to insure that such parts of the yarn package shall not be of adiameter larger than that properly corresponding to the number of layersor coils of yarn wound into them. h

The parts of the yarn package 71 wound against the taper pieces y' willthus be wound so tightly as to be prevented from becoming larger thanthey should be for the number of layers or coils of yarn wound.

Ordinarily the difference between the surface speeds of the differentparts of the taper piece j and between the taper pieces j and thecylindrical part of the driving roll b will be insufficient to cause anyobjectionable rubbing. or polishing of the yarn but in some cases as forexample in winding very ffine or very soft yarn in which it is desirablein order to guard against objectionable rubbing or polishing o the yarn,one or both of the taper pieces j used'according to this invention inwinding yarn into cylindrical packages is or are an capable of beingturned relatively to the cylindrical part of the driving roll by contactwith the carrier in the earlier art of the formation of a packageand aterward by contact with theyarn wound thereon.

- In Fig. 4: is showna driving roll with one taper piece j formed in onewith the cylindrical part and very advantageously by the driving roll I)being formed as a cylindrical tube and expanded at the one end to formthe taper piece j and wlth one taper piece j separate from thecylindrical part and loose so that it may be turned around the shaft 01relatively to the cylindrical part. Theloose taper piece j shown in Fig.4: like that shown in Fig. 1 may be of any suitable material for exampleadvantageousl of vulcanized fiber or of metal and is ormed at itssmaller end with a shoulder so that it may be made to enter the adjacentend of the cylindrical part of the driving roll I) and is secured inposition lengthwise of the shaft (4 by means ofa collar Z made to entera recess in the taper piece j secured in position upon the shaft (4 bymeans of a screw Z.

In Fig. 5 is shown a driving roll 7) with two taper pieces j separateand loose from the cylindrical part so that they may each be turnedaround the shaft a relatively to the cylindrical part. Each of the loosetaper parts 7' which may be of any suitable material, for exampleadvantageously of vulcanized fiber or metal, is formed and secured inposition similarly to the loose taper piece shown in Fig. 1'.

In the use of a driving roll 6 with a loose taper piece j shown in Fig.4:, the loose taper piece j will or may be driven either by frictionagainst the shaft a or by contact with the carrier or yarn wound thereonin the commencement and earlier stages in the winding of a yarn packagei and in the use of the driving roll Z) with two loose taper pieces jshown in Fig. 5, the friction between the taper pieces j and the shaft awill cause them to turn and revolve the carrier f by contact with it orwith yarn wound upon it but after the yarn package a con tains coils ofyarn sufi'icient to bring its surface sutliciently into contact with thecylindrical part of the driving roll, the yarn package will be drivenpartly bythe cylin; drical part and the taper piece j fast therewith inthe case represented in Fig. 4 and by the cylindrical part in the caserepresented in Fig. 5 and the yarn package will determine the speed ofthe loose taperpiece or pieces j which will then act like the taperpiece j shown in Fi 1. In other respects the action of the drivingrolls 1) and taper pieces 7' shown in Figs. l and 5 is similar to thatof the driving roll I) with taper pieces 7' in one with it shown in Fig.3.

The provision of taper pieces j to receive contact of the ends of yarnpackages and especially of the smaller ends of conical yarn packages andthe ends of cylindrical yarn packages during the formation of such yarnpackages very effectively overcomes the tendency of yarns particularlysoft yarns especially if wound in an open wind for-- mation to be woundor built of diameter larger than the intended diameter correnewnesssponding to the number of layers hr coils of yarn wound into the yarnpackages at the ends and especially at the smaller ends of conicalackages and at both ends of cylindrical pac (ages and the formation ofdriving rolls .in tubular form with one or each end eX- panded to form ataper piece is a very simple and convenient way of forming the taperpieces and avoiding any interval in which yarn may catch in cases inwhich it is possible for the taper pieces to be in one with the adjacentparts of the driving rolls with which they are to be used;

Loose taper pieces for use in the manner hereinbefore described adjacentto the driving rolls which are driven to effect winding may be appliedto or on driving rolls of any forms at one or both ends thereof and maybe mounted and kept in position in other ways than those illustrated inthe accompanying drawings and described herein by way of example.

What we do claim as our. invention and desire to secure by LettersPatent is 1. In a winding machine, a driving roll, a tapered roll.mounted adjacent one end of the driving roll to be turned in relationthereto and increasing in diameter in the direction from the adjacentpart of the driving roll and means for rotatably mounting said taperedroll. a
